Suppose \({\mathbf {v}}[1]=\{1\}\). We do the proof with the help of some lemmas. Finally, we analyze a modification of the mechanism where budget balance is achieved without designating any agent as the residual claimant.

Hence, our mechanism converges to efficiency at a linear rate as the number of agents grow. \end{aligned}$$, $$\begin{aligned} p_i(0,v'_{-i})=p_i(0,v_{-i})=p_i({\mathbf {v}})= -\frac{\theta }{n}. Hence, by Properties P0, P1, and P2, we have \(f_i({\mathbf {v}}')=0\). (18) implies that, Using \(f_1(x_2,v_{-2})+f_2(x_2,v_{-2}) \le 1\), we simplify this to get. Recently, studies on redistribution mechanisms have attracted increased attention in the research area of mechanism design to achieve a desirable social decision among self-interested agents. But \(v_1 > x_2\) implies that \(f_1(x_2,v_{-2}) \ge 1-1/n\) and \(f_2(x_2,v_{-2}) \le 1/n\). This simplifies to \(p_i(0,v_{-i})=-\frac{\theta }{n}\), as desired. (2), we get, where the second equality follows from step 1. We modify the dynamic pivot mechanism of Bergemann and Välimäki (Econometrica, 2010) in such a way that lump-sum fees are collected from the players. Hence, \(M^*\) is DSIC. Now, for any \(x_2 \in (v_3,v_1)\), Lemma 2 implies that \(f_j(x_2,v_{-2})=0\) for all \(j > 2\). We then move on to general mecha-nism design settings, where we prove guarantees on the social welfare achieved by Faltings’ mechanism. \end{aligned}$$, $$\begin{aligned} f_i(v_i,v_{-i}) \ge f_i(v'_i,v_{-i}).

Though title is budget balanced, one cannot acheive budget balanced provided mechanism is AE+DSIC. This follows from the top-only property of our mechanism. We show that the modified mechanism satisfies ex-ante budget balance as well as ex-post efficiency, periodic ex-post incentive compatibility, and periodic ex-post individual rationality, as long as the Markov chain representing the evolution of players' private information is irreducible and aperiodic and players are sufficiently patient.
